The little back-and-forth between EMINEM and MARIAH CAREY has just taken a SERIOUS turn. Eminem has dropped an absolutely LETHAL dis track, which was apparently prompted by Mariah’s video for her single, “Obsessed”.

In some of the scenes in that video, Mariah was made up as a guy a pretty CONVINCING guy, actually and a lot of people thought she was trying to take a dig at Eminem.

Mariah DENIED it (and we believed her, since her disguise included dark hair and a thick goatee) but regardless, it set Eminem OFF.

Yesterday, he dropped a track called “The Warning” and it goes after Mariah and her husband, NICK CANNON, HARD. Here are a few highlights:

Eminem opens the track by saying, quote, “Only reason I dissed you in the first place is because you denied seeing me now I’m pissed off.”

Some quick context: Eminem started all this with a track called “Bagpipes from Baghdad”. In it, he takes a few shots at Mariah and Nick and then raps about wanting to take Mariah “back” from Nick. That was the first dis.

Also, Eminem has been claiming that he dated Mariah for about six months back in 2001 but Mariah has always denied it.)

Later, he raps, quote, “Oh gee, is that supposed to be me in the video with the goatee? Wow Mariah, didn’t expect ya to go balls out. (B-word), shut the (eff) up before I put all those phone calls out. When you was wilding out. Before Nick, when you was on my (rhymes with STICK).”

Eminem seems prepared to PROVE that he had a fling with Mariah. He alludes to having personal pictures and voicemails. And then he talks in graphic detail about what he claims was their only FULL-ON sexual encounter.

In that part, Eminem actually embarrassed himself slightly by admitting that he, well, finished too early. He raps that Mariah was so disgusted by the mess, that she almost got sick. For real.

The song goes on and on alternating between attacks and threats before ending with this: Quote, “I ain’t saying this (crap) again, ho. You know what it is. It’s a warning shot for before I blow up ya whole spot

“Call my bluff and I’ll release every (effing) thing I got including the voicemails right before you flipped your top.”

Speaking of that, the end of the song features what COULD BE pieces of those recordings. But all we know is that it’s an unidentified woman who sounds like Mariah who refers to herself as “Mary Poppins.”
